Sorry Clint
If Peter Grosz ever did something on the Fokker B-types (outside what's in his small general book with Volker Koos) it is unknown to me.
Trainers usually generate quite a low interest from even enthusiast, so they are basically less researched than the more "sexy" types. Never understood why really, since if it wasn't for trainers, well there would be very little flying done at all....
Yes, let's hope Jack Herris continues with his range of German manufacturers.
Pity they are mostly pictorials, but as long as all known Bestellnummer are listed, I am happy!
Cheers
